Multiply both numbers by 20 to read 80/100... 80/100 = 0.80
2 x 2 x 5 x 5
12 and 100
Multiply them by 100 - as you would with even numbers. So 5, as a percentage is 5*100 = 500%
As a product of its prime factors: 2*2*5*5 = 100
How about: 4 times 25 = 100
They are: 1*4*25 = 100
4 and 100
That means that you are supposed to multiply both numbers.
It's unclear whether you want two numbers that add to a sum or multiply to a product. 25 x 4 = 100 25 + 75 = 100
If you've written that correctly, there aren't two whole numbers that satisfy those conditions. -20 and -5 add to -25, but multiply to 100. -25 and 4 multiply to -100, but add to -21.
As a product of its prime factors: 2*2*5*5 = 100
81 and 9 if you add them. 4 and 25 if you multiply them.
